How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 4 = 3.12
  3. Check: Work backwards: 3.12 ÷ 4 × 100 = 78%.

In a spreadsheet: =78%*4. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

What the result means

3.12 is the 78% share of 4. The remaining 22% is 0.88, and the two parts add back up to 4.

Discounts: 78% off an item priced $4 saves $3.12, so you pay $0.88.

Adding and taking away 78%

Increasing 4 by 78% gives 7.12 and decreasing it by 78% gives 0.88. These do not cancel out: raising 4 by 78% and then lowering the result by 78% ends at 1.5664, because the second 78% is taken of a bigger number.
